Since it is a regular cursor handling, the result set a multiple row fetch into an array data structure will do the job.
Here an example
DCL-S RsLCsrC01 SQLType(Result_Set_Locator);
DCL-DS DScsrC01 Qualified Dim(100) Inz;
CompanyNo Char(15);
CompanyName Char(35);
Street Char(35);
Country Char(4);
ZipCode Char(9);
City Char(35);
End-Ds;
DCL-S RowsCsrC01 Int(5) Inz(%Elem(DSCsrC01));
DCL-S SavSQLEr3 Like(SQLER3);
//---------------------------------------------------------------------------------------------
// M A I N P R O G R A M
//---------------------------------------------------------------------------------------------
*INLR = *On;
Monitor;
Exec SQL Call GetCompany('GmbH & Co');
Exec SQL Associate Result Set Locator (:RSLCsrC01)
with Procedure GetCompany(VarChar());
Exec SQL Allocate CsrC01 Cursor For Result Set :RSLCsrC01;
Exec SQL Fetch Next From CsrC01 For :RowsCsrC01 Rows
into :DSCsrC01;
SavSQLER3 = SQLER3;
If SavSQLER3 > *Zeros;
For Index = 1 to SavSQLER3;
Text = %Trim(DSCsrC01(Index).CompanyNo) +' ' +
%Trim(DSCsrC01(Index).CompanyName);
Dsply Text;
EndFor;
EndIf;
Exec SQL Close CsrC01;
On-Error;
Dsply PGMSDS.MsgText;
EndMon;

Subject: Re: SQL Procedure Result Sets Array Processing
OK, but how do any of these address the OPs question about returning into an RPG array? Except the one that returned several rows into a DS array?

I'd second the recommendation for a UDTF...
Much more flexible than a SP returning a results set..

Hi Buzz,
you can find some info in the Info Center:
https://www.ibm.com/docs/en/i/7.5.0?topic=procedures-returning-result
-sets-from-stored
But from a modern view of SQL I wouldn't recommend using a stored
procedure returning a result set.
IMHO a user defined table function is the better and more modern
"attack vector" as you can use the UDTF anywhere in any SQL query,
where a table is usable.

For external (RPG) UDTF Scott has created some very nice docs:

HTH and kind regards,

I've gotten the go-ahead to do a POC for creating SQL stored
procedures
that returns a result set(s) to an RPG-ILE array. My searches for
articles and code haven't turned up any "complete" articles (although
I've hit on snippets from Jon, Birgitta, etc.).
Anyone know of any good end-to-end articles that I can read to get
up to
speed?
